RaWrite 1.2
-----------
Purpose
-------
Write a disk image file to a 360K floppy disk.
Equipment/Software Requirements
-------------------------------
PC/XT/AT with a floppy disk drive capable of reading and writing a 360K
diskette.
This program uses generic low-level BIOS diskette read/write functions. It
should be portable to nearly every PC in existance. PS/2's should be able
to run RawWrite but this has not been tested.
CAVEAT
------
This program will write ANY disk file to a floppy, overwriting any previous
information that may have been present. If you wish to re-use a diskette
under MS-DOS thats been written to by RawWrite then the disk will need to be
reformatted; all MS-DOS specific information will have been erased.
How to Compile
--------------
TCC rawrite.c
The source code is specific to Borland International's Turbo C 2.01 and has
been tested in all memory models.
Usage
-----
C> RAWRITE
And follow the prompts. All arguments are case-insensitive.
A sample run is shown below. The disk file being written, in this example,
is named DEMODISK and the destination - where the image is being written -
is the B: drive.
This program may be aborted at any time by typing ^C.
Sample Run
----------
C> RAWRITE
RaWrite 1.2 - Write disk file to raw floppy diskette
Enter source file name: DEMODISK
Enter destination drive: B
Please insert a formatted 360K diskette into drive B: and press -ENTER- :
Writing image to drive B:
Errors
------
RaWrite attempts to determine if the diskette is a 360K, 720K, 1.2M, or
1.44M diskette by reading specific sectors. If the inserted diskette is not
one of the mentioned types, then RaWrite will abort with a short error
message.
Errors such as write protect, door open, bad disk, bad sector, etc. cause a
program abort with a short error message.
